Specification of Letters Patent. Patented Apr. 1 5, 1913. Application filed October 25, 1909 Serial No. 524,402.

at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Sole- Pressing Machines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sole pressing machines, and more particularly to that class of solepressing machines which comprise a shoe supporting jack and a sole pressing pad, and which are used to perform the operation of laying the sole.

The invention is intended primarily as an improvement in the sole laying machine disclosed in the U. S. patent to H. A. Daven port, No. 930,272, dated August 3, 1909, al-

though not limited in its applicationto this machine. In the operation of the twin sole laying machine disclosed in said patent it is customary for the operator to jack or unjack a shoe on one machine while the shoe on the other machine is being put under pressure. When the pressing operation is completed the machine is automatically stopped with the padand carrier in lowered position, but the jack marrying cross head remains locked in, its lowered position. It

is necessary'for the operator to reach from' the machine upon which heis jacking a shoe to the other machine to manually release the clutch which holds the jack in its lowered position. This operation consumes considerable valuable time which it is the purpose 'of this invention to save, by providing mechanism acting automatically to release the jack locking mechanism when the sole pressing operation is completed,

With this object in view, the present invention consists in a sole laying machine having its various parts constructed and arranged as hereinafter described and claimed.

A machine embodying the present invention in its preferred form. is illustrated in the accompanying drawings, in which Figure 1 is a view in rear elevation of the machine with a portion of one of the driving pulleys broken away to show underlying parts; Fig. 2 is a side elevation on an enlarged scale of one. unit of the machine with parts broken away; Fig. 3 is a fragmentary sectional plan view of the trip for the automatic releaseof the jack frame; Fig. 4 is a fragmentary side elevation of the same; Fig. 5 1s a fragmentary side elevation of one unit of the machine showing the mechanism for automatically controlling the jack-releasing comprises two shoe supporting jacks, two

sole pressing pads arranged to cooperate respectively therewith, a foot treadle and connecting rod for moving each jack toward its cooperating pad to bring the sole of the shoe supported on the jack into contact with the pad, and a separate shaft and connected mechanism for actuating each pad to force the pad toward the ack with suflicient pressure to properly lay the sole. Each jack and itscooperating pad'is constructed and arranged as in the well known Goodyear sole laying machine, and the mechanism for ac tuating each ack and form to bring the sole of the shoe into engagement with the pad and to lay the sole is also the same as in that machine. The construction and arrangement of these parts and mechanism are clearly illustrated and described in thepatcuts to Ham'm, No. 375,549, dated December 27, 1887, andDavenport, No. 930,272 dated August 3, 1909, and will, therefore, be only briefly described herein. Each jack comprises a heel post 1 and a toe post 2 adjustably secured upon a cross-head 3 which is mountedto reciprocate upon vertical guide rods 4. The rods 4: project upwardly from side standards 5 and are provided with collars 6- a rod 8 to a foot treadle 9, by means of which the cross-head is moved downwardly to bring the sole of the shoeinto contact with the sole pressing pad. Clutch collars 10, constructed as fully disclosed in the patent to Hamm, are mounted to slide upon the rods 4 with the cross-heads 3, said clutch collars acting to lock the cross-heads in their depressed positions until released manually lowest position.

if so 24 is provided which by the operator, or automatically, as will be hereinafter explained.

The sole pressing pads 11 are mounted in pad carriers 12 provided with collars having a sliding engagement with the vertical rods 4. Each carrier 12 is pivotally connected to the upper arm of a toggle lever 14 which is actuated by a link 15 through an eccentric on a shaft 16, the arrangement of the eccentrio and links being such that a complete rotation of the shaft 16 raises and lowers the carrier 12 and the pad supported therein. Each shaft 16 ha'ssecured thereto a gear 17 which meshes with a pinion 18 upon a driving shaft 19. The driving shafts 19 are arranged parallel with each other and each shaft is provided at one end with a driving pulley 20 mounted to rotate loosely thereon and driven by a single belt passing over an idler 21. A friction clutch is provided for clutching each driving pulley to its sha-ft the clutch being of well known construction and being actuated to clutch the pulley to the shaft b a lever 22.

The sha s 19 and the mechanism driven thereby are entirely independent of each other, so that after the driving pulleys are clutched to the shafts the two sole pressing pads are operated independently and the shafts are thrown out of operation independently. In order to enable the movements of both sole pressing pads to be conveniently controlled by the operator a lever is mounted upon a standard projecting upwardly from the base of the machine. The lever is provided with a cross bar 26 which coiiperates with the levers 22 so that the operator may move both clutch collars simultaneously and connect both driving pulleys to their shafts so that the actuating mechanism of both sole pressing pads is thrown into operation. Each mechanism is automatically thrown out of operation after the shaft 16 has made a half revolution, so that each pad is stopped alternately in its highest and its The parts of the machine so far described are the-"same in construction and mode of operation as the corresponding parts of the machine disclosed in the prior Davenport patent heretofore referred to.

The construction illustrated in the drawings as embodying the preferred form of the present invention comprises mechanism whereby the clutch collars 10 are automatically released in a predetermined timed relation with the operation of pressing a sole. In'order to release the clutch collars 10 it is necessary, to raise them sufliciently to free thelevers' 30 from the inclined faces 31 on the cross-head 3 as is fully explained in the patent to Hamm. lm the present instance this is accomplished levers 32 each fulcrumed upon a bolt 33 carried by lugs 34 on the cross-head 3. Said levers are each provided with a lateral projection 36 which is adapted to engage the under side of the body of one of the clutches 10 to raise said clutches. The levers 32 are operated from a rock shaft 38 journaled in the lugs 84 on the cross-head, said rock shaft being provided with arms 40 secured thereon, which are connected to the levers 32 by means of links 41. A coiled spring 44 surrounds the shaft 38 and is attached at one end to said shaft and at the other end to a lug on the crosshead. This spring tends normally to maintain the shaft 38 in the position shown in the drawings. A handle 45 is also secured to the rock shaft 38 whereby said shaft may be rocked manually to raise the clutches 10 to release the cross-head. For the purpose of automatically actuating the rock shaft 38 it is provided with a mutilated bevel gear 46 secured thereto which meshes with a similar gear 47 which spans the horizontal arm 49 of a bracket 50 secured'to one of the lugs 34. The gear 47 is slidably mounted on a vertical shaft 52,- but is prevented from rotation thereon by screws, 53 which enter an elongated groove 54 on said shaft. The lower end of the vertical shaft 52 is journaled to rotate in a bracket 55 secured to a side standard of-the machine and the upper end of said vertical shaft is rotatably and slidably mounted in the projection 49. This construction enables the gears 46 and 47 to always remain in mesh and an operative connection is maintained with the vertical shaft 52 irrespective of the vertical position of the cross-head 3.

A finger 56 is secured to the lower end of the vertical shaft 52 and is adapted to be engaged by a finger 57 secured to a rock shaft 58 journaled in suitable hearings on the side standard of the machine when said shaft is automatically rocked as will be hereinafter explained. By this construction it will be observed that the shaft 52 may be rotated in one direction independently of the rock shaft 58 by swinging the finger 56 away from the finger 57 as when the clutches are raised manually by drawing down the handle 45. Such a movement of the handle 45 causes the rock shaft 38 to be rotated counter-clock-wise, as viewed in Fig. 7, and by means of the gears 46 and 47 the shaft 52 .is rotated so as to swing the finger 56 away from the finger 57, and at the same time the links 41 are drawn down and the projections 36 are raised to engage the under side of the clutches 10. t

A spring 60 attached at its lower end to the base ofthe machine and at its upper end to an arm 59 secured to the rock shaft 58 tends normally to turn said shaft in a direction to release the clutches. It is prevented from so doing by a cam 61 on the shaft 16. This cam engages a roller 62 carried by a lever 63 fulcrumed on a side standard and connected by a link (it with an arm 65 on the rock shaft 58. The cam 61 is provided with a depression 66 which is adapted to receive the roller 62. This depression is so located with r spect to the pad operating mechanism that it comes into register with the roller 62 just before the shaft 16 has completed the half revolution during which i the pad is lowered. When the roller 62 enters the depression 66, the arms 59. and 65 are lowered under the influence of the spring 60, causing the rock shaft 58 to be partially rotated. The finger 57 engages the finger 56 and turns the shaft 52 and with it the gear 47 which in turn partially rotates the gear 46 and with it the rock shaft 38 to swing the arms 40 downwardly and-the ends 36 of the levers 32 upwardly to raise the clutches 10 and free the levers from the inclined faces 31. Thereupon the cross-head is pushed into its uppermost position by the spring 7. Each jack is thus automatically released and raised when the corresponding pressing pad is lowered, without requiring any attention or manipulation on the part of the operator. As the shaft 16 completes its half revolution the roller 62 rides out of the depression 66, thus returning the parts to normal position so that they will not interfere with the proper operation of the clutches 10 when the 'jack.

is again depressed to bring the shoe carried thereby against the. pressure pad.. o
